To all whom it may concern:

Be it known that I, BIRDSILL HOLLY, of Lockport, in the county ofNiagara and State of New York, have invented new and useful Improvementsin Vises, of which the following is a specification.

This improved vise is a bench-vise which is designed both for metallicand wood Work. The vise proper consists of a hollow supporting-mandreland a second hollow sliding mandrel iitting in and sliding' within thesupporting-mandrel. The two mandrels carry a series of jaws fordifferent kinds of work, arranged radially around the mandrels. Thesliding mandrel is operated by a shaft screw-threaded at one end, whichextends through the sliding mandrel and screws into a nut fixed to thesupporting-mandrel. The supportingmandrel is held in a holder ofpeculiar construction, which is bolted or otherwise permanently fixed tothe bench, preferably to one corner thereof. This holder is what may beappropriately termed a three-way holder, since with it thesupporting-mandrel may be se'- curely and rigidly held in either avertical position or in two horizontal positions at right angles to eachother. The supportingmandrel is held from turning` in the holder bymeans of a set-screw, which also enables it to be adjusted vertically.The supporting-man-- drel is further held from rotation when the vise isemployed for heavy work by interlocking teet-h carried by the mandreland holder, respectively. One pair of the holdingjaws is provided withcircular bores or aper- .tures in each jaw, which may serve as bearingsfor a removable drill or for holding other tools employed by thecarpenter or machinist.

The vise is illustrated in the accompanying drawings, in which- Figure 1is a side elevation of the vise when the same is in a vertical position,showing a drill mounted therein. Fig. 2 is a central vertical sectionthereof, partly in a plane indicated by the line 2 2 in Figs. 1 and 5,and partly in a plane at right angles thereto, as indicated by the line2 2 in Fig. 1i. Fig. 3 is a side elevation of the vise when the same isin a horizontal position, in which a pair of pipe-holding jaws replacesthe drill. Fig. i is a cross-section in a plane indicated by the line 44 in Fig. 1. Fig. 5 is a cross-section in a plane indicated by the line5 5 in Fig. 1. Fig. 6 isa detail View of the three-way holder, and Fig.7 is a detail view of the pipe-holding jaws.

A is a portion of a carpenters or other bench, to one corner of whichthe three-way holder B is securely attached. This holder is a skeletonframe, having six preferably circular apertures C C, oppositely arrangedin pairs on the six sides of the holder, so that an axial line throughthe center of` one pair of apertures shall be perpendicular to axiallines through the centers of the other two pairs, the three axes havinga common center. The bench is formed with an aperture, D, immediatelybeneath the aperture in the bottom of the holder.

E is the hollow supporting-mandrel, preferably circular incross-section. This supporting-mandrel is held by the three-way holder,and may be placed ltherein through any opposite pair of the apertures CC. This mandrel fits nicely and closely in the apertures C C, so that itcan have no lateral movement therein. Since the apertures and mandrelare both preferably circular, the mandrel is held from rotation in theholder by a setscrew, F, tapped through one wall of the holder, andwhich bears against the outer surface of the mandrel. This setscrew alsoholds the mandrel at any height to which it may be vertically adjustedin the holder to suit the user or the character of work employed. Thisset-screw is so mounted in the holder that its axes if continued wouldpass through the common center of the three axial lines passing throughthe centers of the six apertures in the holder. Thisis an importantfeature, since in whatever position the mandrel maybe placed theset-screw will act upon it with equal efciency, and hence only oneset-screw need be employed. At one end this supporting-mandrel isprovided with radial jaws G H I J, preferably formed integrallytherewith and with their faces perpendicular to the axis of the mandrel.The bore of this mandrel extends axially throughout its length; but atthe other end from the jaws the bore is contracted in diameter andinternally screw-threaded to constitute a nut, L.

Fitting and sliding within the bore of the fixed mandrel is theslidingmandrel M, which is slightly less in length than the fixedmandrel. This sliding mandrel carries on its outer end radial jaws G III J, corresponding with the fixed jaws on the fixed mandrel, with theirfaces opposed to and parallel with the faces of the fixed jaws. Thesliding mandrel is also provided with a longitudinal axial bore, throughwhich passes the operatin0-sl1aft N. This shaft at its outer end isprovided with an enlarged head, which forms a shoulder, a, to preventthe shaft slipping through the bore of the sliding mandrel, and with anoperatinghandle of usual construction. The shaft at its other endextends beyond the sliding mandrel, and this extension is screw-threadedto fit in and co-operate with the nut L on the support ing or fixedmandrel. Screw threaded nuts or washers l) l) are screwed on the shaftagainst the inner end of the sliding mandrel to prevent any longitudinalmovement of the shaft in the sliding mandrel and to compel the slidingmandrel to slide in and out when the shaft is turned. Since the bore ofthe fixed mandrel and the sliding mandrel are preferably circular, thesliding mandrel is prevented from rotation within the fixed mandrel bymeans of a removable nut, c, attached to the exterior of the sliding`mandrel, which slides in a longitudinal slot, d, in the fixed mandrel.

By means of the radial arrangement of the jaws four pairs of jaws areprovided, which are constructed to be adapted to different kinds ofwork. The jaws G are formed with broad faces to adapt them to holdwood-work and constitute a woodvise. The jaws H, opposite the jaws G,are narrow and furnished with steel faces e c to adapt them to metalworkand constitute an iron-vise. Between the jaws G II on one side are smalljaws I for light work, which constitute a bracket-vise. Opposite thejaws I is a fourth. pair of jaws, J. This fourth pair of jaws may beconveniently used in conjunction with the woodjaws G to give a moreextended bearing-surface fol long work; but their principal use is ashangers for the attachment of other tools. For this purpose each jaw isprovided with a circular bore, f, the axes of which are parallel withthat of the mandrel.

In Figs. l and 2 the jaws K are shown as hangers for a drill-shaft, O,carrying a drill, P. The bore fof the movable jaw or hanger .I has asmaller diameter than the bore in the fixed jaw, so that the drill-shaftis inserted in position by passing it through the fixed jaw. Thedrill-shaft throughout the greater portion of its length is of adiameter to fit nicely in the bore of the fixed jaw; but its outer endis contracted, forming a shoulder at g, so as to fit in the bore of thesliding jaw. The extreme outer end of the shaftis screw-threaded, andwhen the shaft is in position, with the shoulder g abutting against theface of the sliding jaw, the screw-threaded end projects beyond thesliding jaw, and to this end an operating crank-handle, Q, is screwed.The handle an d shoulder g prevent the drill-shaft sliding in itsbearings.

R is a removable and adjustable collar slipping over the nut end of theouter fixed mandrel, being held in any desirable position by a set-screw71., and it carries the drill plate or plates S, which hold the workoperated upon by the drill. the drilling progresses, the drill isadvanced by adjusting the sliding mandrel by means of the operatingsorenshaft.

In Fig. 3 thedrill is replaced by a pair of pipe-jaws, T T, which havescrew-threaded holding-Shanks 1T, which pass through the bores ff, andare held in position by nuts m m. Other tools may in a similar manner beattached to the vise.

fhen the vise is used in a horizontal position, as in Fig. 3, and isemployed on exceptionally heavy work held near one end, the setscrew Fmay and sometimes does prove insufficient to hold the supporting mandrelfixedly in position; hence one at least of the vertical faces of theholder is provided with a series of fixed teeth or cogs t t, which areengaged by corresponding cogs, w fw, on the outer mandrel. These lockthe mandrel and hold the same from rotation.

Not only does the capability of the quick and ready adjustment of thevise to horizontal or vertical positions to and away from the bench andthe raising and lowering of the same, in all of which positions it maybe fixedly and securely held, render the vise in itself applicable toall kinds of work, but different sides of the same work under treatmentmay be operated on. without removing the work from the jaws by simplyunloosening the set-screw F and rotating the vise if it is in a verticalposition, or by reversing its position from right to left (or viceversa) if in a horizontal position.

I claim as my invention- 1. The fixed holder formed, as described, tohold the fixed portion of a vise in either a horizontal or a verticalposition, in combination with the fixed portion of the vise and thesliding portion carried by said fixed portion, substantially as setforth.

2. The fixed three-way holder provided with holding-apertures on its sixsides, in combination with a vise constructed, as described, so that itmay be held in any opposite pair of said apertures, substantially as setforth.

3. The fixed three-way holder provided with holding-apertures on it-ssix sides and a vise which may be inserted in any opposite pair of saidapertures, in combination with a setscrew carried by said holder andbearing against said vise, the axis of said screw being substantially inline with the center of the holder, substantially set forth.

4. A vise having four fixed jaws extending radially at right angles toeach other, in combination with four movable jaws extending radially atright angles to each other and IOO IIO

jaws, one of each mandrel formed with oppositely-arranged bores orapertures, and a drill having a bearing in the apertured jaw of thesliding mandrel, whereby it may be advanced by movement of said mandrel,and the shank of said drill extending through the aperture in the jaw ofthe fixed mandrel, in combination with a removable and adjustabledrill-plate supported bythe fixed mandrel, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
